The S521 end mill from Dormer is a high-precision tool specifically designed for demanding milling applications in hardened materials. With a nominal diameter of 10 mm and a corner radius of 1 mm, this end mill offers an optimal combination of stability and flexibility. The overall length of 70 mm and a cutting length of 11 mm allow for versatile applications, while the neck relief improves accessibility in tight spaces. The TiSiN coating provides increased wear resistance and enhanced surface quality of the machined parts. The end mill is equipped with four cutting edges that ensure efficient chip removal and uniform machining. With a helix angle of 45° and a negative cutting angle of -10°, this end mill is ideal for various milling processes, including shoulder milling, plunge milling, and ramp milling.

• TiSiN coating for increased wear resistance
• Optimized for milling applications in hardened materials
• Neck relief for improved accessibility
• Suitable for various milling processes such as plunge milling and helical milling.
